Are there long-term miners on server PSUs around here ? How long has your server PSUs been lasting ? Average time before going dead ? Got early deffective ones ?
Due to their almost non-existent warranty time (30 days), I am skeptical to choose them over ATX PSUs which have 10 years warranty as I fear I might need to buy numerous ones over the span of few rigs lifetime cycles, then I am not so sure about actual savings, all things considered (reselling of ATX replacement units of never models in the long run)

They should last longer than consumer grade PSU's. These are designed to run 24x7 for years on end in servers after all.

well, after query, server PSUs' (refurbished!) resellers are eyeballing a longevity of 1.5 years - 2 years, not more (with some rare cases less than 1 year or above 2 years), past any warranty time in all cases

therefore, considering :
- twice units of server PSUs favoribly run closer to 50% load rather than 90% (ATX)
- zero resale value of server PSUs (dead units) against a resale value of 30%-40% of ATX psus, eventually from a newer model of a replacement during the 10 yr warranty time around year 4-6
- despite a 3% efficiency boost in favor of server PSUs underloaded
...the attractiveness of server PSUs does not look evident
actually in my case (considering electricity costs, shipping costs, etc), ATX psus would appear more cost effective from year 1 to year 10, no matter how I manipulate the figures

(side story, you don't see a giant cloud mining company like Genesis running their GPU rigs from server PSUs but from ATX. Was it studied ?)

you can roll with atx's I use them on my lower power builds.

but once you get to a 1200 watt and up build the delta 2400 watt servers are better.

i never build big gpu rigs.

but I do mine some
avalon 721's
avalon 741's
bitmain s-9s

nothing seems better for them then the delta 2400 watt gear.

I pull only 1100-1350 watts per psu.
so psu is relaxed so to speak.

no atx really thrives at 1350 watts
I have run 1500 watt roswewill tokamak titanium
I have run 1600 watt evga titanium
I have run 1600 watt evga platinum
I have run 1600 watt evga gold
I have run 1500 axi platinum

none of them really do well on the antminer 14th s-9's
